To all 'whom itV may-concern: i

ELKIN, a'

of New York, haveinyented or discovered certain new and. useful inprovementsv -1n -Power-Driven Vehicles, of which the following is a specification, referencebeing had therein to the accom anying drawings.

This invention has or its object to provide auxiliary means whereby-the speed of a motoror 'power-drivenv vehicle may be in' creased or accelerated through the medium of rotating fan propellers acting on the air, and therebyaugmenting the propulsion power ap lied to the driving. wheels ofv the vehicles to which the invention may be applied.4 To this end the motor or lpower-driven vehicle `has suitably vmounted thereon one or more fan propellers which are'preferably electric-` ally driven at an exceedingly Vhighspeed o f rotation so that the said propellerswill have approximately -the amount o traction on the air that a screw ropeller would have on water in driving a 'oat or vessel; and thus the ordinary driving mechanism ofthe vehicle will be assisted in propelling the same, and by vehicle` will be steadie thisdistribution of the-propelling force the and the vibrations thereof reduced.v In the case ofan electrically driven vehicle, auxil-A iary motors may be provided for driving the vehicles.

propeller motors may be drivenfrom tpovfvker e vor use are illustrated in the vaccompanying drawings, in which Figure 1 shows'fin outline, an electric carr having'theinvention ap lied thereto. Fig.-

2 is an end elevation of t e same; and Fig. 3

shows, partly in vdotted outline, a motor-vee hicle having .the invention applied thereto.;

Referring tothe-drawings, 12 denotes .any electric car equipped with an electric motor. ormotors, conventionally indicated at 13,1

of any ordinaryor suitable construction, and which motor vor kmotors are geared tothe driving wheels in any Well-known manner.. Prefe at thesarne time lessenin then `iar `or vibration 'of the motor-driven ve icle in its movements erably in the case ofl an fan propellers- 14,. ydriven by motors 15,v mounted near the upper corners ofthe car, will be these Wi in the' same'cirouit with the motors 'which drive the Wheels ofthe car, so as to be under the control ofthe motor'man.' To serve their purpose as propellersthe fans 14 are, ,of

electrically ldriven'- car, such as is indicated'rn the Adrawlr'i'gs, two

rovided at each end thereof, and ll)preferably be electrically connected course', all driven in `the same-direction,

Where several fans are used on onevehicle, and the said fans are freely ex osediendwise to. the open air so -aste be e ective' as pro'- pellers. As the driving mechanism of the'fcar will, as is customary, be reversible, itI will be understood-that the fan' propellers'A- shown will be Vreversed when 'the driving f'mechanism is reversed for thepurpose of'running-,the' car in either direction, these propellersbeing started-and stopped as the motorof ,the car is started and stopped'by the motorman in the usual manner. fThe fanpropel1ers'14 are carried by the motor shafts 16 any snitable manner.

- ",To roperly sustain the usual or this weight' of the rim prope er motors the can is preferably constructed with astrong metal ,frame-work??? comprising lsuitable bracesso as to giveit great strength and. rigidity. `Thefa'n pro'- pellers are artlyinclosed by segmental guards 2,0 w ch, however, are'suficiently In the form of the invention shownin Fig.

open to permit free movement of the air.

3 the fan propeller 14 is driven by the: motor 158L 'suitably mounted at the rearjof the car or motor vehicle ,18, and which motor-vehicle `motor, at 19, geared, as is customary; tothe driving wheels or "axle ofthe vehicle.`

battery conventionally.represented ati-21".

l The invention 1s not to be understoodas being limited in its-,juss to' any .particular form of motor or engine; the motor ef'the`ve'f-j l hicle shown 'm Fig. 3', while preferably an`i1 i ternal combustion engine', maybe of any-a '-5 proved kind, as willbe understood,'while t e" 'electric mot-or.- o r motors of thecarl 'shown in Figs. 1 and 2 may be'driven'by p'ovverclef` or underground conductor.'
